Web Information

The Mastercycler® Pro offers users unique flexibility for use in PCR applications.
These thermal cyclers feature extremely fast heating and cooling rates (up to 8°C/s with silver blocks), intuitive graphic programming, and a display to indicate cycler number in a network. All units feature Triple Circuit heating technology with Fast, Standard, or Safe temperature control modes. Cyclers are upgradable to real-time PCR. Satellite System use allows users to control up to five units with one control panel or to expand to thirty units with a computer network using CycleManager pro software.

Models are available in three block formats, with the ability to operate in various configurations. Plates, tubes, or strips may be used depending on specific application requirements. All formats come with gradient SteadySlope® technology to ensure heating and cooling ramp rates remain consistent. All units are also equipped with the vapo.protect technology, which keeps evaporation to a minimum.
